Update.
2000-06-10 Ulrich Drepper <drepper@redhat.com> * pthread.c (__pthread_create_2_1): Optimize a bit. * internals.h (invalid_handle): Also test for p_terminated != 0. (nonexisting_handle): New function. Same as old invalid_handle. * join.c (pthread_join): Use nonexisting_handle instead of invalid_handle to test for acceptable thread handle. Reported by Permaine Cheung <pcheung@cygnus.com>.
